When this quantum effects happen just outside the "event horizon" of a black hole, there is a chance that one of these virtual particles will pass through the event horizon and be sucked forever into the black hole while its partner virtual particle remains outside the event horizon free to float in space as a real particle (Hawking Radiation). In our previous work [1], we claim that antimatter particle has anti-gravity characteristic, therefore, we claim that during the Hawking radiation procedure, virtual matter particles have much larger chance to be sucked by gravity into the black hole then its copartner the anti-matter (anti-gravity) virtual particle. This leads us to the conclusion that hawking radiation is a significant source for continuous generation of mostly new anti-matter particles, spread in deep space, contributing to the expansion of space through their anti-gravity characteristic. -
Aleksei A. Abrikosov 1928–2017
Aleksei A. Abrikosov 1928–2017 A Biographical Memoir by M. R. Norman ©2018 National Academy of Sciences. Any opinions expressed in this memoir are those of the author and do not necessarily reflect the views of the National Academy of Sciences. ALEKSEI ALEKSEEVICH ABRIKOSOV June 25, 1928–March 29, 2017 Elected to the NAS, 2000 Shortly after the 2003 announcement that Aleksei Abrikosov had won the Nobel Prize in Physics, a number of colleagues took Alex to lunch at a nearby Italian restau- rant. During lunch, one of the Russian visitors exclaimed that Alex should get a second Nobel Prize, this time in Literature for his famous “AGD” book with Lev Gor’kov and Igor Dzyaloshinskii (Methods of Quantum Field Theory in Statistical Physics.) Somewhat taken aback, I looked closely at this individual and realized that he was deadly serious. Although I could imagine the reaction of the Nobel Literature committee to such a book (for a lay person, perhaps analogous to trying to read Finnegan’s Wake), I had to admit that my own copy of this book is quite dog-eared, having been put to good use over the By M. R. Norman years. In fact, you know you have made it in physics when your book gets a Dover edition. One of the most charming pictures I ever saw was a rare drawing in color that Alexei Tsvelik did (commissioned by Andrei Varlamov for Alex’s 50th birthday) that was proudly displayed in Alex’s home in Lemont, IL. It showed Alex with his fingers raised in a curled fashion as in the habit of medieval Popes. -

Vol. 1, No. 4, 2013, pp. 45-51. doi: 10.11648/j.ijass.20130104.15 Abstract: In the present research work, we calculate the frequencies of Hawking radiations emitted from different test black holes existing in X-ray binaries (XRBs) and active galactic nuclei (AGN) by utilizing the proposed formula for the 8.037× 10 33 kg frequency of Hawking radiation f= Hz and show that these frequencies of Hawking radiations may be the M components of electromagnetic spectrum and gravitational waves. We also extend this work to convert the frequency of Hawking radiation in terms of the mass of the sun ( M ⊙ ) and then of Chandrasekhar limit ( M ch ), which is the largest unit of mass. Keywords: Electromagnetic Spectrum, Hawking Radiation, XRBs and AGN Starobinsky showed him that according to the quantum 1. -

Interview with Alexander Ivanovich Pavlovskii
Interview with Alexander Ivanovich Pavlovskii Interview with Alexander Ivanovich Pavlovskii t the end of the intense week-long meeting at Los Alamos in November 1992 among scientists from Arzamas-16, Los A Alamos, and Sandia, we met with the head of the Russian delegation, Alexander I. Pavlovskii, to talk about his expe- riences as a nuclear-weapons scientist in the former Soviet Union. Pavlovskii had been a protegé of Nobel Peace Prize winner Andrei Dmitrievich Sakharov. At the time of our conversation, he was Deputy Chief Scientist and Head of the Fundamental and Ap- plied Physics Department of the All-Russia Scientific Research In- stitute of Experimental Physics at Arzamas-16, Russia. Two translators were present: Elena Panevkina, who was by Pavlovskii’s side at all meetings with non-Russian speaking scientists, and Eugene Kutyreff from the Laboratory’s International Technology Division. We thank both of them for their patience and endurance. Just as we were preparing to send this interview to Pavlovskii for his review, we learned of his sudden death on February 12, 1993. We were honored to have met him and moved by the candor and depth of feeling he expressed during our interview. Many scientists at Los Alamos knew Pavlovskii well, and we hope they will find this interview a fitting memorial to an exceptional man. 82 Los Alamos Science Number 21 1993 Interview with Alexander Ivanovich Pavlovskii Los Alamos Science: Tell us how different.
